 | 试试这段代码：
System.Diagnostics.EventLog log = new
System.Diagnostics.EventLog("Application", ".", "TestApp");
log.WriteEntry("'%1'", System.Diagnostics.EventLogEntryType.Information);
log.Close();
然后打开 控制面板 => 管理工具 => 事件查看器 => 应用程序日志，看看写入的日志变成了什么？
应该是“'%1'”，但却是一堆很奇怪的东东：
''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''%1''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
测试了以下系统，安装的都是 .NET Framework 1.1 SP1，均发现有此问题。应该是 .NET Framework 的问题：
Windows 2000 Server
Windows XP Profrssional SP2
Windows Server 2003

| 问题不在 EventLogEntryType，而是 WriteEntry
根本就写入了错误的日志，而且还错得很离谱。本来应该是“'%1'”，却写入了“''''''''''%1''''''''''”，错误的规律是%1前面和后面的任意字符会被重复很多次。这个 %1 并不是代码的必须参数，而且即使是参数，那也应该是 {0} {1} 的格式啊。
